CAIRO - Young activists held a protest outside Egypt's Chief Prosecutor's office in downtown Cairo Wednesday calling for the release of Ahmed Saad Abu Duma, an opposition activist who was sentenced to three months in jail for assaulting police during a protest last April. The protestors, from the opposition groups Youth for Justice and Freedom and the Public Movement for Change and Democracy, raised banners calling for more freedom of expression and freedom for Abu Duma, a member of the April 6 Movement. They were cordoned off by around 50 black-clad policemen.
